In this course you will learn how to design the type of training that takes advantage of the plastic nature of the athlete’s body so you mold the right phenotype for a sport. We explore ways the muscular system can be designed to generate higher force and power and the type of training needed to mold the athlete's physical capacity so it meets the energy and biochemical demands of the sport.
We also examine the cost of plasticity when it is carried beyond the ability of the body to adjust itself to meet the imposed training stresses. The cost of overextending plasticity comes in the form injuries and chronic fatigue. In essence, a coach can push the athlete’s body too far and it can fail. Upon completion of this course you will be able to assemble a scientifically sound annual training plan.

Training Science

In the first topic you are introduced to the fundamentals of training science. This knowledge underlies your ability to design the type of training that will most effectively improve an athlete’s performance. Essential concepts such as homeostasis, core training principles, magnitude and timing of the training stimulus, and periodization theory are all discussed.

In the 1960s, GAS became the theoretical framework for sports training, because it helped explain how a training stress affected the body and why an adequate recovery was an essential component of the athlete's training program. GAS gave us a better insight into how the structures involved in homeostasis interacted. Two broad categories of homeostatic structures were identified, a group of parameters that were rigid and the other group, that were plastic. The rigid category of parameters cannot be changed through training and the plastic category of parameters can be changed. Rigid parameters are tightly controlled, because they affect the way proteins function. Now, I'm going to move out of the screen for a little bit here, because I want to illustrate what happens to the body and I need the entire screen to do this. Enzymes are built from proteins and are easily destroyed when acidity and temperature is outside their respective desirable range. A coach cannot change the desirable range for the rigid parameters. This is fixed and for this reason, the body shuts down when temperature and acid conditions are too high. High body temperature is a particular problem. The body generates heat due to metabolism. And under normal conditions, excess heat is dissipated through the skin or by the evaporation of sweat. When training in extreme heat, high humidity, or under a hot sun, it is difficult for the body to get rid of the excess heat. Under very severe climatic conditions, core body temperature can rise to a life threatening 106 degrees Fahrenheit or, for those of you in the rest of the world, 41.1 degrees centigrade or even higher. This high body heat damages the protein enzyme structures and they are unable to work properly. Now, another factor leading to overheating is dehydration. A dehydrated athlete loses the ability to sweat and sweating is an important mechanism for eliminating body heat. While temperature can be life-threatening, acid conditions in the body never reach a life-threatening level in healthy athletes. Damage to cells can occurs, but the pain forces the athlete to stop before the acidic conditions become dangerous for the cells. Now, this is not the case with high temperature. An athlete can push themselves until a high temperature causes serious problems. Plastic homeostatic parameters are the most important training component. The term plastic refers to structures that can be remodeled to manage the higher work load. Plastic parameters support the rigid parameters by helping maintain them within a normal range. And enhanced acid buffering capacity stimulated by training helps control the acidic environment for enzymes during intense training sessions. And from a temperature perspective, more blood vessels are built to the skin to improve the cooling mechanisms. Three important plastic parameters affected by training include those responsible for mobilizing the energy resources, building additional structural capacity, and improving the body's defense or immune system capacity. The type of energy resource that is mobilized depends on whether the athlete is training strength, speed, or endurance. In each case, the athlete's genetics determines the upper limit to structural growth. Strengthening plastic parameters usually involves mobilizing the ability of cells to synthesize proteins. This could be protein for muscle, protein to build more enzyme, or to build channels in the cell walls for the entry of fuel supply and the removal of waste. Most structural proteins are built during the recovery periods between the training session. The enhanced structures can improve both the immune system and the energy capacity of the athlete. The body's immune system is essential to adaptation, because training damages cellular structures and repairing this damage requires the immune system to dismantle the damaged cells and replace them with new ones. The type of training the athlete performs determines the type of protein synthesized. In other words, the adaptive response to training is very specific. A speed training session, for example, will stimulate strengthening structures involved in producing speed. Mobilization of the immune system is one of the more critical responses to training. During very stressful training periods, the immune system can become overworked and this is one reason an athlete can get a cold or respiratory system infection. In other words, improvement of the plastic parameters through training help the rigid parameters remain within their normal range, so homeostasis is not as easily disturbed.
